To all whom it may concern:

Be it known that LALBLRT Bnomaciti- Zen of the United States, and a resident'of Chicago in the county of Cook, State of Illinois, have invented certain new anduseful Improvements in Punches.

My invention relatesto punches, particularly hand punches for punchingtickets, cards, etc.

One of the important objects of the in-v vention is to provide such a punch ofsuch construction that the major portion thereoi may be formed integrally from a sheet metal stamping and in which the male and female it can be accurately determined just where punching will take place.

The above and other features of my invention are incorporated in a punch shown in a certain preferred embodiment on the accompanying drawing in which Fig. 1 is a side elevational view,

Fig. 2'is a vertical sectional view,

Fig, 3 is an enlarged sectional view on plane 3-3, Fig.2, Y

Fig. 4 shows the stamped blank from which the body member of the punch is formed up and Fig. 5 is an'enlarged plan view of the "die plate. 2 i

The maln part of the body member A is formed up fronia single piece of sheet metal,

the stamped blank before forming being 'shown'in .Fig. 4:. The blank hasv the main or central-portion "10, u1'e side parts 11 and 12 and the end or grip part 113. The "side parts are separated from the main part by the slots l and, 15. After punching ofthe blank tothes'hap'e shown Fig. 4 it is bent longitudinally substantially along the lines Zr. and b and the side parts 11 and "12 are bent along the lines 0 and (1.

bending the edges 6 and f are-securedtothe lines a, b, o and (Z is preferably gradual so as to give greater strength. Inserted 'between the sides 11 and 12 after bending of serted between the upper ends of the side walls and has the front and rear flanges :17 and 18 extending downwardly againstthe enclosure or chamber 9 being then provided. The plate 16 has the opening 19 for-receiving the die hub 20 on "the die plate '21,;this

screws 22.

stamped blank and at the front thereof are;

the notches 23 and 24 into which thefhori Zontal 'gui'deplate 25 'is secured after bend-' ing of the blank. .This plate has the-hole 26 therethrough in vertical 'registerwith"tl1e hole 27 in the die hub 20, and inthetop'wa'll of the member A is-the guide hole 2 8 I'n*the holes126 and 28 the die pin- 29 "is guided with its axis at all times coincident with the axis of the die hole 27. Both .themn andremale die members are thus supported on the main or body'member Aof the punch.

The 'die pin operating member B 'of'fthe punch is also formed integral of 'sheet metal and comprises the back portion 30'and the strengthening side flanges 31 and 32. The front end 33 of themember B extends between the side walls of the member A"abiove fleets downwardly to be opposite the grip section 13 of thebody member 'A.' '.'At its front end the memberB has the longitudi-- nally extending slot 35 which-receives the reduced section '36 of the die'pin' 29. A short distance rearwardly of the slot 35jthe flanges of 'themember B have openings 3.? for receivingythe hinge or "pivot pin "38 which is secured in the openings 39 and v40 of the member A. v When the member B swung the diepin 29 is given axial movement. A suitable spring 411. interposed between the rib sections. 13 and 34 tendsfto hold the grip ends. apart and thedie'pini29' in itsup'per'position to clear the "slots 14 brought together the pin 29 isshifted yerti- The bending along;

the blank is the plate 16. :The plate 'is'insecured by 111631190? 1'05 and '15 for the entranceof material to be i; punched. When the. grip sections are The die pin is always at right angles with the die hub and the member B of the punch, has no direct connection with the pin but merely causes axial movement there: of, the pin being entirely supported and guided on the member A which also sup-' ports the die hub 20. As the member B is not directly secured to the pin 29 the pin 38 can be placed close to the end of the member, and the punching leverage is thus greatly increased.

Referring to Fig. 4, the said blank has the notch 42 at the front of the body part and in front of the hole 28 providedfor the die pin.

When the punch is formed up the top of the member A'in front of the die pin is open so that the punching operation can be readily observed and the material to be punched accurately aligned with referenceto the die pin. To facilitate such observation a slot 43 may be provided in the plate in front of the pin guiding hole 26. Thewall sections 44 and 45 adjacent the slot 42 are triangular and form the guide surfaces 46 and 47 for guiding the material into the punch.

a At the outer edges .of the side sections 11 and 12 of theblank are the rectangular recesses 48 and 49 which join when the member 'Ais bent into form to provide an outlet opening from the chamber A sliding cover 50 is provided for this outlet, this cover being deflected at its side to provide to discharge the accumulated punchings the ploy a stamping of sheet metal.

cover is slid rearwardly and the punchings shaken out at the outlet opening.

The rldges or beads 53 and 54 besides SEIVlIlg as ralls for the cover, also serve to strengthen the side walls 11 and 12. and the beads are preferably carried around the rear ends of the slots 14 and 15 to strengthen the member A where the greatest strain is apt to occur during operation of the punch.

I thus produce a strong and efficient punch in which the die members are at all times accurately relatively aligned and the male die member is always at right angles with the female die member.

.I have shown anddescribed a preferred embodiment of my invention in which I em- I By employing asheet metal stamping in the construc- -tion' of myv punch, I am enabled to make a :very considerable saving in labor and material without sacrificing rigidity, strength,

or other necessary qualities which are essential in such apunch. By my improved form of punch I am enabled to dispense with con siderable difficulty in the manufacture and assembly of parts or elements heretofore entering into the construction of punches.
